First Rush Brings SDI Multicam ProRes Recording to Apple Silicon Macs

First Rush is a native macOS application designed for on-set editors, DITs, and small production teams that need to capture organized rushes directly from SDI sources. The app records live SDI camera feeds from Blackmagic DeckLink, Blackmagic UltraStudio, and AJA hardware to Apple ProRes .mov files on Apple Silicon Macs.

The project began as a practical on-set editorial tool. While working in production, developer and editor Jin-kyu Han wanted a way to bring live SDI feeds into a Mac, record them as edit-ready ProRes media, and keep the files organized with the kind of metadata that matters later in post. First Rush is built around that workflow: capture the camera feed, preserve useful production information, and move quickly into editorial review.

First Rush can monitor and record multiple SDI inputs, with embedded audio, SDI timecode, REC flag handling, camera labels, file naming, and scene/cut/take metadata. The goal is to make each captured clip easier to identify once it reaches Final Cut Pro, DaVinci Resolve, or another post-production tool.

The app also includes live monitoring tools for set and near-set review. Users can view scopes, apply LUT/CDL-style color adjustments, use playback tools for quick review, and route output to SDI where supported by the connected hardware. A Companion Viewer workflow is also available for remote or secondary monitoring.

For productions that do not need a full cart-scale recording system, First Rush is intended to turn a Mac and common SDI I/O hardware into a compact multicam ProRes recording station. It is especially aimed at teams that already work in Apple Silicon and Final Cut Pro-based environments, but still need traditional SDI capture, timecode, and on-set metadata discipline.

First Rush is available for macOS through the Mac App Store, with more information and downloads available from Editor Han’s website.
